Unity - A scripted object has a different serialization layout when loading error

Question

The game has run on my iPhone 8 Plus before, and it has worked with no issues up until now. Now I get the following output in Xcode during the app's runtime:

I have not used #ifdef UNITY_EDITOR anywhere in my code. The game runs perfectly fine in the Unity editor with no issues or warnings. The game does load onto the phone showing the main menu, but the play button does not progress to the next scene.

Seems to be consistently reading only 32 bytes for each object based on the output.

Any ideas?

Answer 1

I ran into this issue recently. In my case, I had to convert a Windows game to support Mac. The game worked perfectly in the Editor but not when it was standalone.

This is because I forgot to update the includePlatforms in asmdef to include the platform that I was building, i.e. macOSStandalone. (It worked in Editor because I specified "Editor" in "includePlatforms")

Weirdly, I didn't find any Unity docs on what other possible choices are. I found a large list of them here: Unity Multiple Assembly Definition Files Error
